If you're banging your head off the wall like I was looking for the onboard sound card driver for the sis530 chipset and have tried everything else this is the driver for you. Look on the mother board bottom left beside top pci slot, if you see ESS download this driver. It is in zip format. Just create a new folder zip it there then run the setup file. Then you can delete the folder after installation. It worked for me.
